STRING on THREAD CUTTER.

Specification of Letters Patent.

Patented May 26, 1914:.

Application filed January 13, 1913. Serial No. 741,694.

To all whom it may concern Be it known that I, DOROTHY M. MoT- TRAM, a citizen of the United States, resld ing at Los Angeles, in the county of I os Angeles and State of California, have invented new and useful Improvements in String or Thread Gutters, of which the following is a specification.

This invention relates to string or thread cutters or devices whereby strings, threads and the like may be conveniently severed.

It has for its object to provide a cleviceof the character stated which will be superior in point of relative simplicity and inexpen siveness in construction, convenience in use and mounting, durability, positiveness and efficiency in operation, and which wlll be generally superior in point of efliciency and serviceability.

The invention has more particularly for its object to provide a cutter of the general character stated which can be convemently attached to the dress or wearing apparel of the user, being provided with a pin or polnted portion permitting such attachment and detachment.

In a modified form, the improved device is readily attachable to a desk or other support where it may be in convenient position for use as a cord or twine cutter.

With the above and other objects in view, the invention consists in the novel and useful provision, formation, conformation, construction, association and relative arrangement of parts and features all as hereinafter set forth, shown in the drawing and finally pointed out in claims.

In the drawing: Figure 1 is a side elevation of a thread or cord cutter organized in accordance with the invention; Fig. 2 is a similar view taken at right angles to the showing in Fig. 1; Fig. 3 is a fragmentary showing of a blank out of which the device shown in Figs. 1 and 2 may be conveniently and inexpensively formed; Fig. 4c is a view of the showing in Fig. 3 taken in a direction of vision at right angles to that of Fig. 3; and Fig. 5 is a fragmentary sectional view taken upon the line X X Fig. 1, and looking in the direction of the appended arrows.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawing, the improved thread or cord cutter shown therein comprises two cutter members, A and B of which the member A is formed with cutting edge portions or which embrace the cutting edge portion 2) of the member B, such edge portions (4 being in angular relation to the edged portion 6 so that a thread or cord or the like C drawn between the same and directed toward over-lapping portions of said edged portions will be severed by the same. The cutter members A and B are mounted upon or in connection with a body member D, and preferably said cutter members and body member are integrally formed of a single length of metallic stock X, preferably steel wire for ordinary purposes, such length of wire being bent or twisted and distorted or flattened in the proper manner to produce the cutter members, the body member and the other parts of the device. To form the cutter member B the stock X is preferably flattened, as at 6, to project laterally from the main portion of the stock, forming a cutting blade, and to form the cutting member A the stock is preferably flattened and projected laterally in both directions as at 7 the wings of such projection being bent around to produce a channel formation, as shown in Figs. 1 and 5, such channel formation receiving and embracing the blade formation 6, and being provided with the cutting edges a, the blade 6 being provided with the cutting edge I) which in part lies within and in part lies without the cutting edges a, there being an angular relation between the same as shown in Fig. 1. The stock above the flattened portion 6 is bent into an end loop or eye 8, and the stock between the portions 6 and 7 is bent into a loop 9. Continuing from the portion 7 the stock X is formed into a broad transverse loop 10 lying at right angles to the plane of the cutter members A and B. The adjacent portion of the stock X is developed into 2. preferably straight pin barv 11 for connecting the entire device with the dress or wearing apparel of the user, or for otherwise supporting the device. Theofiioe of the broad loop 10 is to prevent the entire device from turning around when pinned to wearing apparel, such result being obtained by this loop bearing against the body of the user and thus preventing the rotation of the pin bar 11. The thread or cord is readily brought into position to be cut by passing it beneath the loops 8 and 10 whereupon a downward movement will cause-the severance between the cutting edges of the cutters A and B.

The entire device is extremely simple and inexpensive in construction, light in weight and neat and attractive in appearance, and it is manifest that many modifications as to the specific features of construction and arrangement of the parts may be made without departing from the spirit of the invention.

Having thus described my invention I claim and desire to secure by Letters Patent:

1. A cutter for thread or the like, con prising in integral construction, a single pin bar provided at its upper end with a broad loop extending laterally of the pin bar in both directions, and cutter members arranged in a plane in angular relation to the plane of said loop; said cutter members having converging edge portions between which the thread or the like is passed, and comprising an edged channeled portion and an intruding edged portion.

2. A cutter for thread or the like, comprising in integral construction, a pair of cutter members, a single pin bar and a transverse member for preventing rotation of the pin bar; said parts and members being formed of a length of metallic Wire which is flattened at predetermined parts to produce edged cutter members, a portion of the wire between the cutter members being bent to hold the cutter members in working relation, and the remaining portion of the Wire being looped to form said transverse member and thence extended to form said pin bar.

3. A cutter for thread or the like, comprising in integral construction, a pair of cutter members, a pin bar and a transverse member for preventing rotation of the pin bar, said parts and members being formed of a length of metallic wire which is fiattened at predetermined parts to produce edged cutter members, a portion of the wire between the cutter members being bent to hold the cutter members in working relation, and the remaining portion of the Wire being looped to form said transverse member and thence extended to form said pin bar; the wire Where flattened to produce one of said cutter members being thereafter bent to produce spaced edged portions embracing the portion of the other cutter member.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
